As with all machinery, pumping systems will decline in efficiency over time, either due to abnormal operating conditions, or through normal wear and tear. To keep the system functioning at peak efficiency it’s important to monitor pumping performance on a regular basis, but it can be difficult to pick up gradual declines in performance by observation only. Unless regular checks on the system are made, it’s likely the decline in efficiency won’t be noticed, until the system fails to the point where there are significant equipment and or crop losses.
